An endoscope comprising a shaft comprises an imaging system arranged in the shaft and an illuminating system which allows light emitted by a light source to emerge at the distal end of shaft, wherein the light source comprises at least one light emitting diode. The light source comprises at least two light emitting diodes which emit light in different spectral ranges, and the light of the at least two light emitting diodes emerges spectrally additively mixed from the illuminating system.
